         5 . The plastic blasting agent A according to  claim 1 , wherein the at least one particle PA 1  comprises
 3 to 95% by weight of at least one polymer KA 1 , 
 5 to 97% by weight of at least one foreign particle FA 1 , and 
 0 to 10% by weight of at least one additive and/or adhesion promoter. 
 
     
     
         6 . Use of a plastic blasting agent A, comprising at least one particle PA 1  made from at least one polymer KA 1 , and at least one foreign particle FA 1  for the surface treatment of a component that was produced by additive manufacturing. 
     
     
         7 . Use of a plastic blasting agent A according to  claim 6 , wherein the component, which was created by means of additive manufacturing, was produced using a method selected from the group consisting of powder bed methods, light-curing methods, or extrusion methods. 
     
     
         8 . Use of a plastic blasting agent A according to  claim 6 , wherein the surface treatment of the component comprises depowdering, compacting, smoothing and/or surface roughening. 
     
     
         9 . Use of a plastic blasting agent A according to  claim 6 , wherein the foreign particle FA 1  is not an abrasive grain. 
     
     
         10 . Use of a plastic blasting agent A according to  claim 6 , wherein the polymer KA 1  has a Shore hardness of 10 Shore A to 95 Shore D. 
     
     
         11 . Use of a plastic blasting agent A according to  claim 6 , wherein the polymer KA 1  is selected from the group consisting of polyamides, resins, polyesters, polystyrenes, polyolefins, polyvinyls, rubbers, polyvinyl chlorides, polyphenylenes, polyethers, polyurethanes, polysaccharides, polyimides, polyacrylates, silicones and blends and copolymers thereof, and the foreign particle FA 1  is from the group consisting of metals, passivated metals, iron, steel, minerals, soot particles, carbon fibers, paint particles, ceramics, polymers, alloys or glasses. 
     
     
         12 . Use of a plastic blasting agent A according to  claim 6 , wherein the component is produced by an additive manufacturing or printing method and wherein the component is produced from a material selected from the group consisting of polyamide, thermoplastic polyurethane, aluminum-filled metal, polyamide, glass-filled polyamide, carbon-reinforced polyamide, and combinations, blends, or copolymers thereof.
